Working Principle of 73S8023C-IM/F

73S8023C-IM/F uses the asynchronous serial communication protocol for data communications with other devices, and uses differential transmission mode for data receiving and sending. The specific working principle of this device is that: all data is input from the RS-232 terminal, converted with TTL level and transferred to the opposite device through the differential transmission mode.

The differential transmission mode mainly has two transistors for reception switching. A transmitting transistor and a receiving transistor are used to transmit signals. When a transmitting transistor is opened and closed, its corresponding receiving transistor is opened and closed at the same time, and a differential voltage is generated between two overlying ends. This method can reduce the interference of external electromagnetic fields and make transmission more stable.
